All necessary hot water boiler controls and secondary plumbing are in place and pre wired, and the vessels easily fit through a three foot wide doorway, resulting in a very quick start-up. Firing rate goes up to 2100MBTU, and many millions of BTU’s can be delivered by creating an efficient, fully modular system of many vessels operated by our control panel.

Standard features include nationally known parts and controls that are quickly available at most supply houses, allowing for easy quick and easy repair and maintenance, which can dramatically reduce down time.

Design

The Series 2000 is manufactured to exceed ASME Section IV standards and typically is used to provide supply temperatures from the coil of between 140-180°F, yet can accept extremely low return temperatures (below 100°F) without shocking the boiler. The Space Heating side of this boiler can provide supply temperature up to 200°F, and return temperature can go as low as 140°F. The temperature of the coil water is impacted by the temperature of the Space Heating side because the coil is immersed in that water. These vessels feature 70 vertical firetubes, each of which is 2″ diameter, 12 gauge steel and fitted with a high-efficiency turbulator for maximum heat transfer. The combustion chamber is fully water-backed, with burners that are UL listed.

Safety

A well-made, rugged vessel is naturally a safer. ZHONGYUAN Combination Boilers also have a firebox design that is completely backed by water, along with safety controls that results in a very safe and secure package.
